Thank you for all of your time! This site is the cat's a$$..Where have I been for all these years....
In my haste I forgot to mention that there is an impact load during changeover that I haven't quantified yet. Apologies as this is an important fact. Would this alter the opinion of going to...
- Fatigue crack propogation
- ~50 ksi
- Max = 32 ksi, Mean = 0 ksi, Min = -32 ksi(compression)
- 2.058M cycles. We need infinite life with corrosion resistance.
Thanks for your input.
I need to compare H1150 vs H900 in an axially loaded part. The H1150 parts have failed where expected(stress conc.) and I wonder if H900 will fill the bill even though the Ut of H900 indicates severe brittleness. For reference, the machined surface finish is 32 Ra and the stress concentration...
I have found that burr's and poor surface finish aids in galling. We use alot of 300 series sst npt threaded fittings and whenever we run them over a general buffing wheel we never have problems. Impractical for high volume manufacturing, but maybe this will help. We have also seen this when...
